I'd rather not go into the reasons - Dave Neely has done a good job dissecting the book, plus I was at Goldstein's talk at whatever convention that was. I do own a copy, and it has some nice pictures in it.
Like Dustin said, get a "Fishes of (yourstate)", and a Peterson's guide. Larry Page IS a definitive author on natives.
I read Neely's review. Some of his criticisms I also share such as Goldstein's species choices. Still though there was a lot wrong with it I was not aware of. Despite this I still cannot think of a better book on the subject of native fish keeping. State books and field guides are great and I own several but none of them go over captive care. Goldstein's book is still the best book on native fish keeping and evidently this is a sad thing.
